This heel grounding device provides protection for staff on the move by offering a ground via proper flooring surface, wearing the conductive ribbon inside the shoe or sock assures proper electrical contact with the user. The ribbon connects to the conductive rubber to complete the circuit between the operator & flooring. A rugged surface mounted 1 megaohm resistor is standard & visible. These devices should be worn on both feet to ensure consistent grounding. Features: 1) Current limiting resistor: ±1MΩ2) Safe and reliable3) Electro dissipating time less than 0.1s 4) Adjustable at will5) Rinsing Resisting6) Used in cleanroom
